Thanks Dora,
I have been going through the arduino library,the source code only and i started going through the workflow. I don't need the complex functionality rather a UID read would be enough.
anyway i will continue my research and I don't get enough time daily as I need to do these all...
Hi Dora,
Sorry that if I had not followed the etiquette . I am really in search of the library that supports the MFRC 522 RFID .There is one for the arduino which is almost stable but nowhere i find that for the PIC18F or PIC16F.
I searched many a times and could not find any results .
If you...
Hi All,
I have an RFID MFRC 522 module which is bought for the arduino ,**broken link removed**
This is using the SPI. But I don't see any libraries for the same for the PIC 18 series. Is anyone knowing about any such libraries for the PIC18F series ?
I know many libraries are there for the...
Thank you. I was not having the permission to upload as attachment . that is why i uploaded to file sharing.
yes, I have disabled the WDT and even then it has not difference.
Only in proteus it works fine where as in actual development board it is not.
Thanks for the reply
I am posting the project as a zip file. Also I have tested the same in proteus and it is working fine.
I am having some issues doubts here, I have the 20MHz crystal in my development board and this code is written considering that in mind.
But when I set the PIC Processor...
Hi all,
I am having a PIC18f4680 with which I am trying to write on LCD. I am using the xLCD library and has just modified the portB to PORTD. Created a new header xLCDMod.h and copied all the XLCD.h contents to that and modified the port to PORTD. Also added copy of all the *.c files of the...
Thanks and it got resolved as I kept my modem far away from the PIR . And since PIR is isloated its not interfered by the signals. Also any phone signals can make interruption
For the high-low interrupt where I have set INTEDG=0, the RB0 is tied to 5v through 10k resistor.When the interrupt is not there, 5v is what is shown on RB0, and when PIR interrupts, the RB0 comes to 0.
But as mentioned, this RB0 comes to 0 from 5 when the USART interrupts. But when this RB0...
I am creating a GSM project with GSM input to RX/TX of the PIC16F877A .Also I am using a PIR sensor which outputs 3 v and is connected to RB0 .
INTEDG is set to 1.When an interrupt happens, an LED is made to toggle.
I have a few problems here :
When the RB0 is connected to 5v using a switch...
What these USARTHandleRxInt() and sendSMS(); will do is to just set the flags and in the main while loop only the other actions are performed.
My main issue is that when the RCIF is triggered for serial input, the INTF is also triggered and calls the SendSMS().
This happens only when I connect...
Hi All,
I am doing a project using the SIM 900 and PIC16F877A. I am able to read the UART and send through UART as well. I am having ISR code which has 2 blocks,one handles the UART interrupt to store the serial data ,and another check for the RB0 interrupt.
I have enabled the INTE,GIE...
Hi All,
I am having a SIM900 module. **broken link removed**
I was trying to communicate it with and display the response in LCD. But somehow I was having some issues of getting LCD working all the time. In the mean time I connected the USB of the GSM module with the PC and used the GSM...
